Description

[0001] Cooling-water heating type heater [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cooling water heater. More particularly, the present invention relates to a cooling water heater which is provided with a heater sensor for measuring the temperature of the heater.

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a coolant-heated heater, and more particularly to a coolant-heated heater that heats coolant for heating the vehicle interior.

Vehicles powered by engines powered by gasoline, diesel, and other energy sources are currently the most common forms of vehicles, but these automotive energy sources also require new sources of energy due to a variety of causes, such as environmental pollution as well as reduced oil reserves. One of the technologies that is near to the practical use stage is a vehicle driven by a fuel cell as an energy source.

However, in a vehicle using such a fuel cell, a heating system using cooling water can not be used unlike a conventional vehicle having an engine using oil as an energy source. That is, in the case of a conventional vehicle using an engine using an oil as an energy source as the driving source, a lot of heat is generated in the engine, a cooling water circulation system for cooling the engine is provided, . However, since a large amount of heat such as that generated by the engine does not occur in the driving source of the vehicle using the fuel cell, there has been a limit to such a conventional heating method.

Accordingly, in the fuel cell vehicle, various studies have been conducted, such as adding a heat pump to the air conditioning system and using it as a heat source, or providing a separate heat source such as an electric heater. Among them, the battery heater can heat the cooling water more easily without greatly affecting the air conditioning system, and the actual use is widely practiced at present.

Fig. 1 shows Japanese Patent Laid-Open No. 2008-056044 ("heating medium heating device and air conditioning device for a vehicle using the same, " 2008.03.13), which is one of conventional cooling water heating type heaters.

The cooling water heater of Japanese Laid-Open Patent Publication No. 2008-056044 has plate-shaped fins disposed on upper and lower portions of the PTC electrode plate causing heat generation, cooling water flowing through the plate-shaped fins, and heat transfer efficiency So that the cooling water can be heated more effectively.

However, such a coolant-heated heater has a problem that it is difficult to obtain a sufficient effect of heating the coolant, and the problem including this is described below again.

First, since the heat source (PTC electrode plate) is inserted into a separate component, the number of parts increases, and the volume and weight increase. Second, the heat generated from the PTC electrode plate can not be completely transferred to the cooling water, and a part of the heat is transferred to the outside to generate heat loss. Third, there exist various objects such as an insulating layer on the heat transfer path from the PTC electrode plate to the cooling water, thereby increasing the heat resistance and thus the heat transfer efficiency is inferior. Fourth, the design of the cooling water pipeline and the electric supply line circuit becomes complicated when the cooling water heater of this type is mounted on the vehicle. Moreover, since the size of the cooling water heater is large, actual mounting becomes difficult.

That is, there is a demand for a coolant-heated heater that can effectively cool cooling water, can be easily manufactured and installed, can reduce volume, weight, unit cost, and can secure safety.
